Field of the Invention The present invention relates to a distribution device for disposing a steel strip on an upper surface of a steel plate and a steel structure assembling facility having the distribution device. Welding multiple long steel plates by welding the long sides
A steel bar material distribution device for assembling a long bar or other steel bar material on a large plate used for a hull or bridge, and a steel bar for the long side welding line of the large plate using the same. The present invention relates to a steel structure assembling facility capable of selectively manufacturing a steel structure in which materials are arranged in parallel and a steel structure in which steel members are arranged at right angles to a welding line.

[0002]

2. Description of the Related Art For example, a plurality of longitudinals are vertically erected on an upper plane of a lower panel and welded to a ship bottom, a deck, a bridge, or the like.
A steel structure is used in which the upper panel is placed on a longge and welded between them. In the assembly of this steel structure, for example, 2
20m or 30m on a 0m x 30m panel (large plate)
Vertically position the longes (strips) of the longitudinal direction, and perform tack welding by horizontal fillet welding at each point in the longitudinal direction of the longitudinals, temporarily attach the required number of longitudinals, and then perform full welding to complete the length of the longitudinal. To the large plate.

FIG. 1 shows an example of a production line for such a steel structure. A wide and long steel plate, which is a material of the large plate 3, has its width direction aligned with the transport direction x, and
Then, the long side is conveyed immediately below the single-sided welding device 2 and welded to the previously conveyed steel plate. The large plate 3 formed by sequentially welding the required number of sheets is moved to the place of the material distribution device 5. There, using the material distribution device 5, the longes are distributed on the large plate, and the longes are tack-welded to the large plate by automatic welding or manual welding. The large plate on which the required number of longes have been temporarily welded is conveyed to the place of the longe welding device 6, where the entire length of the longe is welded, that is, the main welding is performed. This kind of assembly equipment is known
No. 20381 and Japanese Patent Publication No. 52-12999.

[0004] A material distribution device 5 shown in FIG. 1 holds longes arranged in a skid (not shown) in parallel in the y direction while maintaining a posture parallel to the y direction, and transports them on a large plate. , Positioned at the required position on the large plate. Therefore,
Even on the large plate, the longes are parallel to the y direction. That is,
The longitudinal direction of the longe is the y direction, and is parallel to the plate joining line of the large plate extending in the y direction.

[0005] When a longe is temporarily welded to a large plate, for example, as disclosed in Japanese Patent Application Laid-Open No. 3-234370, steels are opposed to each other in the thickness direction so as to sandwich the longe standing on the large plate. The ball is protruded and pinched to position in the direction along the horizontal plane, and furthermore, the pressing shoe or roller is pressed against the upper surface of the longe to press the longe against the large plate, and the pressed portion is temporarily welded. I have. By the way, before such a temporary assembly, it is necessary to arrange a longitudinal on a large plate. Therefore, the applicant of the present invention has disclosed Patent No. 3111.
No.128 positioning device was developed. This is equipped with five sets of clampers on the y-beam on the x-carried gantry, sandwiches the longie in the place, transports it on the large plate, positions it, and drives the holding member down. Press the longe against the large plate and temporarily weld the pressed part.

[0006]

However, the clamper for holding the longe is provided with a horizontally rotating support arm and a holding arm respectively on two opposing legs of an upside-down U-shaped base frame. The arm is equipped with a hydraulic cylinder that protrudes the holding shoe, and when holding the longe, the support arm and the holding arm are moved from the retracted position parallel to the longitudinal direction y of the longe to the holding position orthogonal to y (parallel to x). Attitude), and hold the longe by projecting the holding shoe with a hydraulic cylinder. Since a horizontal rotation space for the support arm and the holding arm is required, the space between the two opposing legs of the upside-down U-shaped base frame is wide, and the width of the base frame in the x direction (the thickness direction of the longe) ( (Longitudinal direction of the longitudinal), and the longitudinals cannot be arranged at a short pitch. In addition, the clamper is mounted on an upside-down U-shaped base frame,
Equipped with a mechanism for horizontally rotating these and a hydraulic cylinder for projecting the shoe, the device becomes large and heavy, and the y-beam and the portal trolley supporting a plurality of such clampers become robust, large, and expensive. It becomes equipment. In addition, the work speed is reduced due to the high weight carried.

Further, even when the steel strip is pressed down to the steel sheet, the steel strip and the steel sheet adhere to each other due to unevenness of the lower bottom of the steel strip, warpage or bending of the steel sheet, or uneven thickness of the steel sheet. It may be difficult.

[0008] On the other hand, there is a case where there is a demand for distributing the material so that the longitudinal is perpendicular to the welding line on the large plate. Although not applied to a large plate, the drawings in Japanese Utility Model Application Laid-Open No. 63-122759 show that a support beam for supporting a plurality of fillet welders is supported on a portal frame and rotatable about a vertical axis. In addition, a welding facility that enables fillet welding by rotating a welding machine support beam by 90 degrees regardless of which of the two orthogonal directions y and x is the longitudinal direction of the strip is disclosed.

Japanese Patent Application Laid-Open No. 8-84939 of the applicant of the present invention relates to the distribution of the longe to the large plate. In this case, a horizontal support beam that supports a large number of longitudinal clampers is suspended and supported on a traveling platform so as to be pivotable about a vertical axis, and the longitudinal is parallel to the large plate in either of two orthogonal directions y and x. Can be distributed.

However, a mechanism for supporting a horizontal support beam for supporting a large number of longitudinal clamps so as to be pivotable about a vertical axis requires the structure of the rotary support part to be rigid. become.

It is a first object of the present invention to provide a distribution device capable of arranging steel strips at a relatively short pitch.
A second object is to provide a distribution device that can relatively easily and easily adjust the position of a steel strip relative to a steel sheet, and a third object is to make the steel strip and the steel sheet more closely contact each other. A fourth object is to simplify the work of holding and releasing the strip material, and a fifth object is to provide a low-cost material distribution apparatus.
The purpose of. Further, there is provided a steel structure assembling facility capable of disposing a steel strip in any of two directions in a direction perpendicular to a steel plate, without requiring a distribution device for driving a horizontal support beam to pivot about a vertical axis. It is a seventh object of the present invention to provide a steel structure assembling facility which realizes this with a mechanism that is as simple and / or inexpensive as possible and that has stable plate support.

When the plate (3) is an unequal thickness plate having a different thickness depending on the location on the x and y planes, for example, it is a large plate formed by welding steel plates having different thicknesses by different thickness single side welding. Even in this case, since the turning support devices (17, 18) can expand and contract in the vertical direction z, substantially all of the friction rollers (24) hit the lower surface of the plate (3) and support the plate (3), so that the plate (3) is supported. Stable and smooth turning.

The structure for driving the lifting platform (11, 12, 13) upward and supporting the plate (3) downward through a plurality of turning support devices (17, 18) distributed on the x, y horizontal planes is simple.

For example, when the plate (3) is a large plate having an unequal thickness, the cushion member (27) of the turning support device where the plate is thick is greatly shrunk, and the cushion member (27) of the turning support device where the plate is thin is less shrunk. Then, the turning support devices (17, 18) expand and contract so that the supporting loads are automatically equalized. Therefore, the support of the plate (3) is stable, and the turning is smooth.

5) and a roller base (31) for rotatably supporting these rollers.

Since the elastic member (36) comes into contact with the lower surface of the plate (3), the friction is strong, and the effect of preventing the plate (3) from skidding, particularly the effect of preventing the skid of a large plate of unequal thickness, is high.

(16) A cushion member (32) for supporting the roller base (31) below is provided. According to this, for example, when the plate (3) is a large plate of unequal thickness, the cushion member (32) where it is thick shrinks greatly, the cushion member (32) where it is thin shrinks little, and The center turntable (15) is pressed against the plate (3) so that the supporting load becomes even. Therefore, the reliability of the side skid prevention of the plate (3) is high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A turning device 4 is installed in a work area of a distribution device 5 on an x-direction conveying line of a large plate 3 in a steel structure manufacturing line shown in FIG. A wide and long steel plate which is a material of the large plate 3 is transported immediately below the single-sided welding device 2 on the transport line 1 with its width direction aligned with the transport direction x, The long side is welded. The large plate 3 formed by sequentially welding the required number of sheets is moved to the place of the material distribution device 5. Then, if necessary, the turning device 4 turns the device 90 degrees. When the large plate 3 is turned by 90 degrees along a plane parallel to the x and y planes by the turning device 4, the material distribution device 5 is driven to the evacuation position closest to the long welding device 6 (x direction). .

The material distribution device 5 distributes longes on a large plate. In this embodiment, the longe is temporarily welded to the large plate by manual welding. The large plate on which the required number of longes have been temporarily welded is conveyed to the place of the longe welding device 6, where the entire length of the longe is welded, that is, the main welding is performed.

FIG. 2 shows an outline of the turning device 4. The lifting platform 12 is located at the center position in the y direction of the
There is an elevating pedestal 11 and 13 between which an opening space for the large plate conveying roller row in the x direction is opened. These lift bases 11-13 are guided by lift guide rollers so as to be able to move up and down in the vertical direction z, and are driven by hydraulic jacks from a lower retracted position to an upper working position and vice versa.

The center point 16 of the central lift frame 12 is located at the center of the large plate transfer line in the x direction. The elevating gantry 11-13 has six turning support devices 17 at a constant pitch on a relatively short radius around the center point 16, and
On the circumference of a relatively long radius, there are 12 turning support devices 18 at a constant pitch. These turning support devices 17, 1
8 have the same structure.

FIG. 3 shows one swivel support device 17 in an enlarged manner. FIG. 3A is a plan view (where the tire wheels 24

There are seven.

The speed reducer 22 is integrated with the speed reducer base 21, and the rotation shaft of the electric motor 23 is connected to the input shaft. The rotation shaft of the tire wheel 24 is connected to the output shaft of the speed reducer 22. Air is press-fitted into the tire wheels 24. The tire wheels 24 have a large frictional force with respect to the steel plate and have high elasticity.

The turning support device 17 and the other turning support devices are also provided with the lifting pedestal 11 so that the rotation center axis of the tire wheel 24 is parallel to a radial line on the x, y plane centered on the center point 16. Alternatively, it is fixed to 12, 13. Therefore, when the large plate 3 is coming, the lifting platform 11
-13 is pushed up to the working position, the large plate 3 is supported by the tire wheel, the large plate 3 is lifted, and the turning support device (17)
When the electric motor (23) is driven to rotate, the large plate (3) mounted on the tire wheel (24) rotates about the center point 16. Since the tire wheels 24 have elasticity and the air cushion 27 has elasticity, the tire wheels 24 of the all-turn support device (17, 18) are pressed against the lower surface of the large plate 3 even if the large plate 3 is not uniform. Then, the large plate 3 is rotationally driven. For example, when the large plate 3 has an unequal thickness, the cushion member 27 of the turning support device where the large plate 3 is thick shrinks greatly, and the cushion member 27 of the turning support device where the thin plate 3 is thin shrinks little, and the supporting load is automatically evenly distributed. The turning support device (17,
18) expands and contracts. Therefore, the support of the large plate 3 is stable, and the turning is smooth.
